Installation Instructions Quick-Mount Visual Instructions for Mechanical Installation Quick-Mount Visual Instructions 1. Rotate the damper to its fail-safe position. If the shaft rotates counterclockwise, mount the “CCW” side of the actuator out. If it rotates clockwise, mount the actuator with the “CW” side out. 2. If the universal clamp is not on the correct side of the actuator, move it to the correct side. 3.

Installation Instructions Mechanical Installation Determining Torque Loading and Actuator Sizing Mechanical Operation Damper torque loadings, used in selecting the correct size actuator, should be provided by the damper manufacturer. If this information is not available, the following general selection guidelines can be used. The actuator is mounted directly to a damper shaft up to 1.05” in diameter by means of its universal clamp.

Installation Instructions Mechanical Installation Short Shaft Installation 30 30 If the shaft extends at least 3/4” from the duct, follow these steps: 1. Determine the best orientation for the universal clamp on the back of the actuator. The best location would be where you have the easiest access to the V bolt nuts on the clamp. 2. Engage the clamp to the actuator as close as possible to the determined location. 3. Lock the clamp in place using the remaining retainer clip. 4.

Installation Instructions Mechanical Installation Rotation Limitation The angle of rotation limiter, ZDB-AF2 US, is used in conjunction with the tab on the universal clamp or IND-AF2 position indicator which comes with the ZDB-AF2 US. In order to function properly, the clamp or indicator must be mounted correctly. Screw secured at these cross hairs Secure angle-ofrotation limiter Screw See Figure A. 40 40 20 Angle of rotation is now set at 40°.

Installation Instructions Mechanical Installation Manual Override Auxiliary Switches The AF series actuators can be manually positioned to ease installation or for emergency positioning. The AF series actuators may be ordered with 2 built-in SPDT auxiliary switches used for safety interfacing or signalling, for example, for fan start-up. The switch position near the fail-safe position is fixed at 5°. The other is adjustable between 25 and 85° of rotation.

Installation Instructions Non-Direct Mounting Methods KH AF Crank KH-AF C k arm Including Retaining Ring CAUTION:: The retaining clip supplied with the clamp is nott used to mount the KH-AFF crank arm. The KH-AF (-1) crank arm is used in non-direct coupled mounting applications. The KH-AF (-1) may also be used to simultaneously direct couple to a damper shaft and provide an additional crank arm connection to a second damper.

Installation Instructions Electrical Operation General Control Accuracy and Stability The AF series actuators utilize brushless DC motor technology. The AF uses this motor in conjunction with an Application Specific Integrated Circuit (ASIC). In the On/ Off versions of the AF, the ASIC monitors and controls the actuator’s rotation and a digital rotation sensing function to prevent damage to the actuator. The AF24… modulating type actuators incorporate a built in microprocessor.

Installation Instructions General Wiring Instructions WARNING The wiring technician must be trained and experienced with electronic circuits. Disconnect power supply before attempting any wiring connections or changes. Make all connections in accordance with wiring diagrams and follow all applicable local and national codes. Provide disconnect and overload protection as required. Use copper, twisted pair, conductors only.
